APIC (advanced programmable interrupt control) advanced programmable interrupt controller.
It consists of two parts:
Io APIC: located in the south bridge, used to handle various interruptions caused by devices on the bridge. I
The working principle of the interrupt controller between different CPU systems is quite different, this article is the sister of "the analysis of circuit breaker in Linux MIPS64R2 PCI", mainly analyzes the principle, interrupt configuration and processing process of broadwell-de x86_64 APIC. And try to answer the following questions:
Why is the x86 used in the IO-APIC/LAPIC framework, and what is
